Sibling discovers they paid $19k in rent while little sister paid $0: 'My dad comes in and tells me I'm [wrong] for not paying rent'

This sibling is discovering with clarity that their sister is their parents' favorite kid! It's got to hurt to discover that your parents favor one of your siblings so strongly, and for this person, that discovery has come with a literal cost. 

Parental favoritism can be pretty subtle, because after all, many parents will never admit they like hanging out with one kid more than another. They'll insist that they have no favorites… but come on, they totally do! As long as they treat all their kids more or less the same, this isn't often a problem. But many family dynamics revolve around one sibling always getting their way while the other siblings get penalized for speaking up about it. 

Most parents don't let one kid live rent-free while the other pays $1000 a month, though! That kind of rent disparity is bound to cause problems. This person found out about it and tried to confront Mom and Dad, and you can read all about how that went down below.
